Does industrial concentration shape the life and death of cities? We identify settlements from historical maps of England and Wales (1790–1820), isolate exogenous variation in their late 19th-century size and industrial concentration, and estimate the causal impact of size and concentration on later dynamics. Industrial concentration has a negative effect on long-run productivity—independent of industry trends and consistent with cross-industry Jacobs externalities. A spatial model quantifies the role of fundamentals, industry trends, and Jacobs externalities in shaping industry-city dynamics and isolates a new, dynamic trade-off in the design of place-based policies.
